About: 74 Ophiuchi

An Entity of Type: star, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org:8891

74 Ophiuchi is a suspected binary star in the equatorial constellation of Ophiuchus, near the border with Serpens Cauda. It is visible to the naked eye as a faint, yellow-hued point of light with a combined apparent visual magnitude of 4.85. The system is located at a distance of 238 light years from the Sun based on parallax, and is drifting further away with a radial velocity of +4.4 km/s. The magnitude 11.5 secondary, component B, lies at an angular separation of 28.1″ from the primary, as of 2008. A visual companion, component C, is magnitude 12.28 and has a separation of 57.9″.

  • 74 Ophiuchi is a suspected binary star in the equatorial constellation of Ophiuchus, near the border with Serpens Cauda. It is visible to the naked eye as a faint, yellow-hued point of light with a combined apparent visual magnitude of 4.85. The system is located at a distance of 238 light years from the Sun based on parallax, and is drifting further away with a radial velocity of +4.4 km/s. The primary member, designated component A, is an aging giant star with a stellar classification of G8III and an estimated age of 1.73 billion years. Having exhausted the hydrogen supply at its core, the star has expanded to 10.5 times the Sun's radius. It is a red clump giant, which means it is on the horizontal branch and is generating energy through helium fusion at its core. The star has 2.4 times the mass of the Sun and is radiating 66 times the Sun's luminosity from its swollen photosphere at an effective temperature of around 5,073 K. The magnitude 11.5 secondary, component B, lies at an angular separation of 28.1″ from the primary, as of 2008. A visual companion, component C, is magnitude 12.28 and has a separation of 57.9″. (en)
  • 74 Ophiuchi, som är stjärnans Flamsteed-beteckning, är en dubbelstjärna i den nordvästra delen av stjärnbilden Ormbäraren. Den har en skenbar magnitud på ca 4,85 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 2 på ca 13,7 mas, beräknas den befinna sig på ett avstånd på ca 238 ljusår (ca 73 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet av ca 4,4 km/s. (sv)
